Curved surface baking molding auxiliary device and curved surface forming method

Abstract

The invention discloses a curved surface baking molding auxiliary device. A lower die is arranged on a lower supporting plate, a convex block is arranged at the upper end of the lower die, and the topend of the convex block is arc-shaped; a first air cylinder and a second air cylinder are symmetrically arranged on the two sides of the lower die; a first side die and a second side die are respectively arranged at one end of the first air cylinder and one end of the second air cylinder; an upper supporting plate is arranged above the lower supporting plate; a third air cylinder is arranged on the upper supporting plate, and an upper die is connected with the third air cylinder through a connecting plate; and the shape of the lower end of the upper die is matched with that of the top end ofthe convex block. The invention further discloses a curved surface baking forming method. The curved surface baking forming method specifically comprises the following steps of brushing glue; carryingout pressure maintaining and pre-forming; reinforcing a formed fixture; carrying out baking and shaping; and carrying out cooling and shaping. By the mode, a product can be extruded in the up, down,left and right directions, so that the bending forming effect is enhanced, and the product quality is improved; and heating sheets arranged in the die, so that the forming time can be effectively shortened, the yield can be improved, and the production cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of curved surface forming, in particular to a curved surface baking forming auxiliary device and a curved surface forming method. Background technique [0002] With regard to bending forming technology, at this stage, the traditional curved surface technology types are mostly plastic, metal, wood, and glass molding. The above materials are used in various fields, such as auto parts, hardware, furniture, electronic communications, packaging and other industries. Molding materials, serious environmental pollution, low recyclability, inconvenient to carry. [0003] As people pay more and more attention to environmental protection, people are more inclined to paper curved surface forming. The curved surface of paper is easy to deform and rebound, and it is difficult to achieve a satisfactory curvature. The wrinkle rate is high, and the product will deform its curvature over time, and it is difficult to meet its...

AI Technical Summary

Problems solved by technology

The curved surface of paper is easy to deform and rebound, and it is difficult to achieve a satisfactory radian. The wrinkle rate is high, and the product will deform its radian over time, and it is difficult to meet its use standards.

The traditional paper curved surface forming method adopts manual forming, which is difficult for employees to operate uniformly. Uneven folds often appear, the damage rate is high, the curvature error of the curved surface is large, there are cases where the curved surface cannot be reached, or the curved surface is too curved, and the production efficiency is low. The production time is long, and the product quality is difficult to guarantee
